I guess the Holy Knights might very well have some fodderish people in them depending on how many of them there are. These three are expecting to take Elbaph with no backup, Dorry and Broggy included, so they should amount to something.
Some of them must also be top or very high tiers to worry Dragon, even if of course not all of them.
If there are only around, say, 6, they will all still clear anyone below Jinbe. If there are a dozen, then this is basically CP9 and some will get soloed by random high tiers.
